This is a Nordic pattern knit hoodie or cardigan from Roial. This item is by Roial, a surf brand, and features a Nordic pattern design with a hood. While multiple examples of this item being sold as used on flea market apps and the like can be found, no official sales information for it as a new item is currently available. It is less than half the original price. It's a very cute design. I bought it at a Roial store. There are no noticeable stains or the like, but there is a feeling of wear, so please only purchase if you understand this.
